DUST AND CINDER GUARD FOR RAILWAY-COACHES.

SPECIFICATION forming part of Letters Patent No. 639,426, dated December 19, 1899.

7 Application filed May 18, 1899. $erial1l'o. 716,622. .(No model.)

To all whom it may concern:

Be it known that I, JAMES SOLOMON Mo- KENZIE, a citizen of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Dust and Cinder Guards for Railway-Coaches; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has relation to dust and cinder guards for railway-coaches.

The object of the invention is to improve the construction shown and described in my application filed March 17, 1898, Serial No. 674,207; and to this end the invention consists in certain features of construction and combination of parts which will be hereinafter fully described and claimed.

In the drawings, Figure 1 is a perspective view taken from the inside of the car. Fig. 2 is a cross-sectional view, and Fig. 3 is a detail perspective View, of a corner of the dustpan and one of its side shields.

In the drawings, 1 denotes the window-sill, 2 the side frames, and 3 the lower sash.

5 denotes the dust and cinder pan, which is of substantially the same construction shown and described in my application above referred to, and is provided with a diaphragm the width of which is less than that of the pan, whereby passages are formed between its edge and the sides of the diaphragm. This pan is also provided with a rotary brush the diameter of which is greater than the width of the diaphragm and which operates in substantially the same manner and by the same means employed as in the construction shown in my aforesaid application. The up per edge of the forward side of the pan is formed with a roll, in which are located spring-actuated bolts 6, which are adapted to engage suitable sockets in the side pieces of the window-frame and be actuated by the handles 7.

8 denotes side shields, the lower ends of which correspond in outline with the ends of the dust-pan. These side shields extend up wardly and are connected to the inner sides of the window-frame, and serve to conduct any cinders or dust that enter the car at the side of the frames into the dust-pan. Near the lower ends of these side shields are inclined plates which extend over the roll of the pan, so that the dust and cinders are con ducted directly into the pan upon the brush.

As the construction of the pan is minutely described and the operation clearly set forth in the application above referred to, it is not thought necessary to enter into a detail description of the construction and operation of those parts which in themselves are not a part of the present invention.

It will of course be understood that various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is I A dust and cinder guard for railwaycoaches, comprising a semicylindrical pan, side shields adapted to be secured to the sides of the window-frame to conduct cinders and dust into said pan, a diaphragm the width of which is less than that of the pan, whereby passages are formed between its edge and the sides of the diaphragm, and a rotary brush, the diameter of which is greater than the width of the diaphragm, whereby when in position, the brush will be pressed against the lower rail of the window-sash in position to catch any cinders and dust which may enter the car under the said rail, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.

JAMES SOLOMON MCKENZIE.

Witnesses: LEONARD O. FALLIN, GEO. FALLIN.
